Description
Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.
Objective
1. Acquire knowledge on how the resistance of a wire is affected by its resistivity, length, and area.
2. Identify the relationship between Current, Voltage, and Resistance.
